(a) 3D orientation of the transducer in the simulation domain. A few cylindrical branches are also shown here to illustrate the random branches’ orientation in the domain. (b) 2D view ($x\text{–}y$) of the random distribution of cylindrical scatterers shown as black circular spots in the uniform white background, corresponding to the case of $b=2.8$ and $N_0=200$.
